That's really impressive, but I think it only works for videos, not still images.
Although it could probably be used for the intro video. My original upscale of that could use some improvement. Unfortunately, I doubt I'll have time to fool with it though...

I'm pretty sure you're right about "only videos". Especially with the discussion of the wavelet flows that originally needed motion vectors, but now can work with just video (which implies that the motion vectors are being calculated from the video). If you can accurately track how the camera is panning over a scene, you can extract a huge amount of additional information from image sequences. Older super-resolution used to work purely by this temporal alignment/stacking process. If you feed all of that information into a super resolution learning system, you get these amazing results. But it doesn't look like anything new on the single image front, unfortunately.
Still, damned impressive. Thanks for the link!

Make a film of all the sprites, run it through that program, then pick out frames and convert them into new sprites

That would be spooky as hell if that actually worked.

I just tried a recent model called Rebout Blend (available
here), which is specifically made for character sprites, and it gives quite decent results with small flats -- notably better than previous models:
It does a very good job with medium flats too (open image in separate window to enlarge):

Oh wow! That really is the best results by far on the small sprites.

Nice job on the artifacts upscales MasonFace, thanks a lot
Also, this new ReboutBlend algo indeed looks really good!

I've been playing more with ESRGAN models lately and found one called Fatality MKII (available
here) which does this to villager close-up faces:
